lTO .ALL WHOM IT MAY CONCERN:

Be it known that I, M. A. RxcnAansoN, of Sherman, in the-county of Chautauqua, and State of New York, i have invented a certain new and useful Improvement in Horse-Powers and I do hereby declare that the fol? lowing is a full and exact description thereof, reference being had to the accompanying drawings, making part ofthis specification'. v

Figure 1 is a plan of my improved-machine.

- Figure 2, a vertical section of the same.

Figure 3,'an end elevation of the balance-wheel and friction-attachment.

Like letters .of reference indicate corresponding parts in/all the'iigures.

My invention consists in the application of an automatic friction-arrangement'to the operating parts of a horse-power, in such a manner that, when a certain degree of resistance is reached, the said arrangement will run free of the parts,l thereby preventing strain or breakage.

It further consists in the special' construction and arrangement of the machine as a whole, whereby great ,simplicity and cheapness are obtained, and the partsmay' be easily detached for transportation or storage.

In the drawings, A'indicats a bed or beam holding the gearing L2 3 4, and sustaining 'the shaft. B, with its balance-wheel C. I I

The' hub a of spur-gear 1 rests looselyn a socket, b, of the bed, so that it may be removed at any time fromplace by simply lifting out.

This hub is made hollow, and a screw-bolt, c, is Vrun, up throughfrom the bottom, being so arranged as not to turn, except with the wheel. Onntop the spur-gear rests a wooden brake, D, extending from side to side, as shown, and havingattach'ed to it the sweep E, to'which the team is hitched.

The screw-bolt passes through this, and a nut, d, screws down o n top, by which the .brake is made to bear with more or less pressure on the'whe'el, as may -be desired. The whole thus constitutes one separate and independent arrangement, detached from the frame of the machine at pleasure.

. The balance-wheel C is similarly arranged, restingloosely on the shaft B,- against shoulder f, and having the friction-arrangement D d clamping it in place, as clearly shown.

The -spccial object in this invention is to obviate sudden shocks that occur in starting and stopping, aud the overstrain that ar-ises from thedisproportion of the power and resistance to the strength of the machinery.

'This eil'ect is perfectly accomplished bythe means here described. The nut, d, can be applied to just such a degree that, when the resistance exceeds a certain limit, the friction-brake D will turn free ou the part 'which it clamps. For instance, if the limit is set at one thousand pounds, the `parts connect, andthegearing will turn till that limit is reached, but if the resistance exceeds that, the brake Vslips free over the clamping-4 surface, which then remains stationary.

This is noft only of importance in preventing strain and breakage of th `e operating parts, but also in obviating sudden check and strain on the horse in starting. In its application-to the balance-wheel, it also prevents breakage from sudden starting and stopping. l

I prefetto make the brake oi' wood, as it isa'ery cheap, and has a degree of natural elasticity that is of great advantage in action.

By making the gear 1 and the balancewvheel C removable, in the manner described, the bed A, with-the remaining operating parts, is in simple and compact form, and the whole can beshppedand stored withl great readiness, since the bed is simply a straight beam, and the 'connecting parts have but little projection, and occupy blt littleI space. In this respect the advantage is obvious over those complex powers of irregular form now in use, whose parts are noteasily separated. The exceeding simplicity and compactness of my machine is one of its greatest merits.

What I claim as my invention, and desire to secure byLetters Patent, is

1. The friction-brake D and nut'ol applied to the operating parts of a horse-power, substantially as and for the purpose set forth.

` `2. The combination and arrangement'of thc driving-wheel 1 with the friction-device D d, in such a manner as to be removable from the bed, eitherseparately or together, by the removal of the nut d, as explained.

In witness whereof, I have hereunto signed my name in tho presence of two subscribing witnesses.
